Child care by choice or by default? : examining the experiences of unregulated home-based child care for women in paid work and training

This thesis aims to uncover the dynamics, causes and outcomes of women's reliance on unregulated home-based child care in Ontario, Canada, and the implications ofthis form of care for women's equality. Drawing on a longitudinal qualitative study, I examine the diverse experience of 14 women using home-based child care and engaged in both paid work/training and care work for children under the age of six, and draw comparisons with users of other forms of child care. I argue that home-based child care involves high levels of instability for continuity of care and is chosen largely as a default position based on economic considerations. It represents a compromise between the demands of social reproduction and paid work/training that entangles mothers in relations of exploitation with care providers. Doing so leaves both mothers and care providers socially and economically vulnerable and relying on social networks to fill in the gaps.

Empathy and Emotion Processing in Mild Head Injury and Sub-clinical Psychopathy

The current study sought to investigate the nature of empathic responding and emotion processing in persons who have experienced Mild Head Injury (MHI) and how this relationship between empathetic responding and head injury status may differ in those with higher psychopathic characteristics (i.e., subclinical psychopathy). One-hundred university students (36% reporting having a previous MHI) completed an Emotional Processing Task (EPT) using images of neutral and negative valence (IAPS, 2008) designed to evoke empathy; physiological responses were recorded. Additionally, participants completed measures of cognitive competence and various individual differences (empathy - QCAE; Reniers, 2011; Psychopathy - SRP-III, Williams, Paulhus & Hare, 2007) and demographics questionnaires. MHI was found to be associated with lower affective empathy and physiological reactivity (pulse rate) while viewing images irrespective of valence, reflecting a pattern of generalized underarousal. The empathic deficits observed correlated with the individual’s severity of injury such that the greater number of injury characteristics and symptoms endorsed by a subject, the more dampened the affective and cognitive empathy reactions to stimuli and the lower his/her physiological reactivity. Importantly, psychopathy interacted with head injury status such that the effects of psychopathy were significant only for individuals indicating a MHI. This group, i.e., MHI subjects who scored higher on psychopathy, displayed the greatest compromise in empathic responding. Interestingly, the Callous Affect component of psychopathy was found to account for the empathic and emotion processing deficits observed for individuals who report a MHI; in contrast, the Interpersonal Manipulation component emerged as a better predictor of empathic and emotion deficits observed in the No MHI group. These different patterns may indicate the involvement of different underlying processes in the manifestation of empathic deficits associated with head injury or subclinical psychopathy. It also highlights the importance of assessing for prior head injury in populations with higher psychopathic characteristics due to the possible combined/enhanced influences. The results of this study have important social implications for persons who have experienced a concussion or limited neural trauma since even subtle injury to the head may be sufficient to produce dampened emotion processing, thereby impacting one’s social interactions and engagement (i.e., at risk for social isolation or altered interpersonal success). Individuals who experience MHI in conjunction with certain personality profiles (e.g., higher psychopathic characteristics) may be particularly at risk for being less capable of empathic compassion and socially-acceptable pragmatics and, as a result, may not be responsive to another person’s emotional well-being.

Investigating the Contribution of Personality and Neurological Disruption to Postinjury Outcome in Athletes with Mild Head Injury

Despite the increase in research regarding mild head injury (MHI), relatively little has investigated whether, or the extent to which, premorbid factors (i.e., personality traits) influence, or otherwise account for, outcomes post-MHI. The current study examined the extent to which postinjury outcome after MHI is analogous to the outcome post-moderate or- severe traumatic brain injury (by comparing the current results to previous literature pertaining to individuals with more severe brain injuries) and whether these changes in function and behaviour are solely, or primarily, due to the injury, or reflect, and are possibly a consequence of, one’s preinjury status. In a quasi-experimental, test-retest design, physiological indices, cognitive abilities, and personality characteristics of university students were measured. Since the incidence of MHI is elevated in high-risk activities (including high-risk sports, compared to other etiologies of MHI; see Laker, 2011) and it has been found that high-risk athletes present with unique, risk-taking behaviours (in terms of personality; similar to what has been observed post-MHI) compared to low-risk and non-athletes. Seventy-seven individuals (42% with a history of MHI) of various athletic statuses (non-athletes, low-risk athletes, and high-risk athletes) were recruited. Consistent with earlier studies (e.g., Baker & Good, 2014), it was found that individuals with a history of MHI displayed decreased physiological arousal (i.e., electrodermal activation) and, also, endorsed elevated levels of sensation seeking and physical/reactive aggression compared to individuals without a history of MHI. These traits were directly associated with decreased physiological arousal. Moreover, athletic status did not account for this pattern of performance, since low- and high-risk athletes did not differ in terms of personality characteristics. It was concluded that changes in behaviour post-MHI are associated, at least in part, with the neurological and physiological compromise of the injury itself (i.e., physiological underarousal and possible subtle OFC dysfunction) above and beyond influences of premorbid characteristics.
